I had a wonderful stay at the apartment. The apartment is located in a thriving area of Thonglor and is a close walk to Ekkamai, where you will find many Japanese cafes and shops. The apartment is on the 5th floor, it is a bit of a walk. However, you will find a nice room with a rooftop garden. You will get a nice breeze from the garden if you open the glass sliding door.
The room is very clean and spacious, with a very well-maintained washroom.
Regarding transit, you can take an authorized motorbike just outside the door of the apartment's entrance for 20 baht to BTS Thong Lo, then make your way to other parts of the city.
Premika was very helpful during my stay and was always available to address my concerns.
